The positions of maximum absorbance for the p and beta bands of the UV-vis spectra of the benzenoid polycyclic aromatic hydrocarbons, PAHs, with molecular formula C32H16 have been predicted by means of the annellation theory. In the C32H16 PAH group there are 46 isomers, 39 of which have not been synthesized so far, thus their characterization and possible presence in the environment remains unknown. The methodology has been validated using literature information for 7 isomers in this PAR group. The results have been satisfactorily substantiated by means of semi-empirical calculations using the ZINDO/S approach. It has been concluded that the annellation theory is a powerful tool for the prediction of the positions of maximum absorbance of aromatic compounds with unknown UV-vis spectra. It is the first time that the UV-vis spectral information on these 39 benzenoid C32H16 PAHs has been predicted.
